Using Firebase_Authentication as Authenticator Provider

• Go to a REST endpoint and configure the authentication provider as "Firebase_authentication"
• Go to your API Client, and paste in the body (raw/json) the successfull response that you got in the Firebase Authentication Login request, as below:

• If successfull you will see the content
• If not, you probably will see the login page

Note: Is important to say that anonymous users don't must have access to see the content/page that you are accessing on these REST enpoints.
